Strata Drilling Group uses Geoprobe® direct push technology to

access small, as well as large testing areas. The Geoprobe®

Model 420M is a compact probing unit designed for tight

spaces. This powerful little machine is designed specifically to be

durable yet as lightweight as possible. At 19” wide and 62” tall

(folded) and weighing less than 425 lb, the 420M can be

manually lifted and carried to remote sampling locations. It can

also be deployed to hard-to-reach and narrow sampling

locations both indoors and out. The 420M is powered by a

remote hydraulic power source.
